FileSystemWatcher

FileSystemWatcher

marshal by reference, disposable

System.IO (system.dll)

class

This class allows you to listen to
the filesystem and respond to
different operations on it. To register a watch on files or
directories, first set Path to the path you wish
to watch. Next, set the Filter property. If you
want to respond to all file changes, set it to an empty
("") string. To watch an individual file, set
Filter to the filename. You can also use wildcards
(such as *) in the filename. You must then also
set NotifyFilter to register the types of events
you wish to be notified of. If you want to monitor the subdirectories
as well, set IncludeSubdirectories.
EnableRaisingEvents allows you to enable or
disable the FileSystemWatcher. The watcher then
exposes the following events: Changed,
Created, Deleted,
Disposed, Error, and
Renamed. An Error is raised if
too many events occur on a filesystem for the watcher to correctly
monitor it.
